BOTTLE-TOP.

SPECIFICATION forming part of Letters Patent N o. 378.108, dated February 21, 1888. Application filed April 15, 1887. Serial No. 234,869. (No model.)

Jersey, have invented a certain new and use-v ful Improvement in Bottle-Tops, of which the following is a specification.

My improved bottle-top is intended more especially for mucilage and analogous semitluids, as hlacking. I will describe it as used for mucilage in applying the same to papers and other objects in a thin coating from time to time, as required. I employ a brush and a sponge com bined as means for applying the mucilage. v These are held by peculiarly sewing upon a perforated block or cap of wood which matches the top of the bottle, and is firmly conned thereon by vashell of metal, which latter is screw-formed and engages with a screw-thread on the exterior of the bottleneck. Its upper portion is slightly coned, with its extreme upper edge flared or coned in the reverse direction. `This form promotes the tight fitting of the removable cap, and also aids in returning the unused mucilage from the sponge and brush to the bottle after each operation. There is an offset or internal shoulder in the metal shell at the junction of the screw-threaded with the conical portion,which matching upon a corresponding ange on the wood confines the latter very firmly to the bottle by simply screwing down the shell with sufficient force.

The accompanying drawings form a part of this specification, and represent what lI consider the best means of carrying out the invention. Y

Figure l is an elevation of the bottle and top, showing thecondition when not in use. Fig. 2l is a corresponding view with the cap removed. Fig. 3 is a central vertical section. The remaining figures show portions. Fig. 4 is a vertical section of the bottle-top at right angles to Fig. 3. Fig. 5 is a corresponding section of the block detached. Fig. 6 is a plan view of the same. Figs. 7 and S show modifications. They are sections corresponding to Fig. 4, but at right angles thereto. Fig. 7 shows the bristles extending through the sponge, and Fig. 8 shows a form in which the bristles are omitted.

Similar letters of reference indicate corremarks, as 'E'.

sponding parts in all the figures where they occur. v

A is the upper portion of the bottle, addior other objects when the bottle is inverted 1 and properly manipulated. The bristles forming the brush C are folded at the lower end and tightly bound together by a twine, c. The brush is secured by a stout thread, m, inserted through transverse holes,the ends being wound around in a groove, b', and secured bytying or cementi ng, or both. There are corresponding transverse holes at the higher level represented. These receive threads p, which engage with the sponge D and hold it -rmly E is a shell of metal, certain portions being designated, when necessary,l by additional Thelower portion, E', is screwthreaded. Above this is a shoulder or offset, E2, which restsiirmly on the flange B of the wooden block B. Above this the'portion E3 is coned, and applies partly against the correspondingly-formed body IB2 and partly around the piece of Vsponge D. The upper edge, E4, is dared outward sufficiently to aid materially in preventing the surplus mucilage from flowing down outside; but c'are must be taken not to flare this portion ont so far as to interfere with the application of the' metal cap G, which performs-the essential function of preventing the mucilage from evaporating 'and hardening in and about the top. The

diameter of the interior 0t` the screw-threaded tightly upon portion E of the shell, so that it will require IOO time that it is pressed inward, so that the screw-threads will favor its entering. The screw-threads terminate a little below the oset E2, preserving a short unthreaded space of a diameter larger than the ysmallest contracted portion between the screw-threads. It follows that when the wooden block B has been forced fully up toits place in the shell, so that it is held loosely therein, and with the upper surface of its flange B receiving a sufficient pressure from the under face of the offset E2, it may adjust itself nicely to the upper edge of the bottle. The metal shell being turned, forcibly presses its shoulder El down upon the flange B and holds it tightly.

One advantage due to the close fitting of the parts is that the block B and' shell E remain engaged when they are temporarily removed from the bottle for supplying with mncilage, or for any other purpose.

The sponge D may be selected of or may be wrought into the form represented in a single piece; or it may be made up of two or more pieces strongly secured by the threads p. The portion of the sponge which covers the brush may become worn by use, so as to let the end of the brush apply directly in the use of the device; or the parts may be made and matched together, with the 4 brush extending quite through the sponge in the first instance, if preferred in any case.

A portion of the mucilage to supply the device may ilow through the brush; but ordinarily the mucilage will fiow mainly through the holes b. The surplus which may be received by the sponge and brush will be returned through these passages to the interior of the bottle after each use. The flaring upper edge, E1, of the metal shell E facilitates this by arresting and retaining the mucilage which may commence to flow down on the outside of the sponge. The top B3, being smaller than the body B, allows the sponge to extend down around the top and be securely fast-4 ened with any required degree of firmness without compressing or in any wise affecting the material of thebrush. I attach importance to this feature of the device, as also to the passages formed by the holes b separate and distinct from those for the brush, which allow the mucilage to flow down and fill the sponge and brush when the device is reversed.

Modifications may be made in the forms and proportions without departing from the principle or sacrificing the advantages of the invention.. I can increase or diminish the number of holes b and of the transverse threads m and p, which confine the brush and the sponge. The extent to which the central portion, B3, of the block B projects upward may vary. It may be suppressed entirely, suitable provisions being made for holding the sponge by threads or other fastenings properly arranged, as the brush C, extending up into the sponge, affords a reliable support for the latter against all ordinary lateral forces.

The support afforded by the brusn is preferable to any which can be afforded by a rigid body alone, because of the elasticity of the bristles, allowing the whole to yield, but promptly returning all to the approximatelycentral position on the bottle-top so soon as the use of the device is completed.

I claim as my invention- I. In a bottle or holder for mucilage and analogous fluids, the combination, with the bottle or vessel A, of a block, B, having holes b independent of the holes for the brush, and of a brush, C, and sponge D, arranged forjoint operation, as herein specified.

2. In a bottle or holder for mucilage and analogous fluids, the block B, having a top,Bi, smaller than the body Bl, the brush C and its fastening means m, and the sponge D and its fastening means p, all combined and arranged to serve relatively to each other and to a bottle, A, as herein specified.

3. In abottle for muclage, the block B, having a flange, B, body B2, and smaller top, B, the brush C and sponge D and their fastening means m p, the block B being provided with holes b, distinct from those which receive the brush material, and the several parts are combined substantially as herein specified.

4. The brush C and holding meansm,in combination with the sponge D and its confining means p, and with the block B, metal shell E, and cap G, as herein specified.

5. In a bottle-top, the block B and separate metal shell E, the latter fiarcd at its top, as shown by E, combined with each other and with the sponge D, bottle A A, and cap G, substantially as herein specified.

In testimony whereof l have hereunto setiny hand, at New York city,this 12th day of April, 1887, in the presence of two subscribing witnesses.

ISAAC POMEROY.
